FLEXIBLE COUPLING FOR SHAFTING.

Application filed April 19, 39M. eriatric. 707,547.

To all whom it may concern! Be it known that I, ALFRED MASURY,

.a citizen of the United States, residing in the borough of Manhattan, of the city of New York, in the State of New York, have invented certain new and useful Improvements in Flexible Couplings for Shafting, of which theiollowing is a specification, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to universal joints of the kind in which thedriving torque is transmitted from the driving member to the driven member through re-enforced fabric material. It is an object of the present invention toprovide a universal joint of this nature which is of simple and inexpensive construction, easy to assemble, flexible in character so asto accomodate the driving and'driven members and in which the drivingtor no is transmitted by elements which extend a ong straight lines coincident with the lines of force of the driving tor ue.

. More particularl the improvements re ate dli till

to a joint whic is characterized by the connection of the driving and driven memthe torque arms are of varying len hs. The cords transmitting the torque rom one member to another are laid in the fabric tangential to the arc of movement of the, shorter torque arms. An illustrated embodiment of the invention wherein the fore of which is the driving shaft and the other of which is the driven shaft with provision for universal movement whereby the two shafts need not be in exact alignment. \Vhilc the universal joint according to the present. invention is equally applicable irrespective of which shaft is the driving shaft and which is the driven shaft, it will shaft with satisfactory results. The approximate end of shaft bcarrics a coupling plate 5. Secured to the plate 6 at its central portion and tothe flanges c a near its periphery is a flexible. disc 0 of fabricated material re-enforced bytension cords coincident with the lines of force set up in the disc during the transmission of driving stresses between the shafts, the arms a on the one hand and the couplingplate b on the other serving astorque arms for the transmission of the driving forces between the respective shafts. The connec- 'tions with the disc may take any convenient form but it is preferred to secure the central hers to the disc on difi'erent radii so that portion oi the disc to the plate 6' by means of an annular series of bolts 15 and to secure the perimeter of the disc to the diametrically disposed flan es a by means of bolts a The heads 0 the bolts may seat against washersor the like on the opposite sides of the disc such as are shown at a in Figure 1 whereby the disc is securely clamped theredill between, and the strain is distributed somewhat over a greater-extent of the disc to minimize the possibilities of the holes in the fabric wearing or tearing. In lieu of Washers for the heads of the bolts 6 a ring or plate 5 may be interposed between the I heads 'oftheholts h and the fabric disc."

By connecting one shattrto the center of the disc and the other shaft tothe perimeter of the disc a connection may bepro'vided which will ermit maximum angularity between the s aft and at the same time transmit the driving torque with facility. lit has been found that the lines of force-set up in the disc when driving torque is transmitted through the disc hetween torque arms did'ering are of movement of the shorter torque arm.

lln order to ire-enforce the disc in the direc-' tion of greatest tension, it is proposed to inhill) in. length are disposed tangentially to the 3 J long dashes and the left hand winding being representedby short dashes in the'drawings. A5 a carrier for the cords the may be embedded in rubber or other suitable ma terial to form the disc 0/ Various changes may be made in the arrangement and disposition of the coupling means carried with the respective shaft ends as well as in the composition and re-entorcement of the disc without departing from the spirit and scope of the invention and no limitation is intended except as indicated in the appended claims.

What I claim is 1. In combination with driving and driven shafts, torque arms of dilferent lengths carried with the respective shafts, a disc operatively connected ,with the torque arms, and tension cords embedded in the disc and disposed in the plane of the disc and tangentially to the arc of movement of the shorter torque arm.

In combination with driving and driven shafts, a disc of flexible non-metallic material, arms formed on one of the shafts, means to connect the extremities of the arms with the disc, a coupling plate carried with the proximate end of the second shaft and of lesser radius than the arms, means to connect said coupling plate to the disc, and tension cords formed within the disc and disposed in the plane of the disc and tangentially to the arc of movement of the connection between the coupling plate and disc.

3. In combination with driving and (lllV- en shafts, a disc of re-enforced fabricated material, diametrically disposed arms carried with an end of one of the shafts. bolts to connect the extremities of the arms with the disc, a coupling plate carried with the proximate end of the other shaft and of lesser radius than the arms, bolts to connect the coupling plate with the disc, and continuous tension cords formed within the disc
